Enalapril Hexal, tablets 20 mg 50 pcs

How to take, the dosage

Enalapril Hexal is administered orally, regardless of meals, with plenty of fluids. Treatment with Enalapril Hexal is prolonged. The drug dose should be adjusted according to the patient’s condition.
Enalapril Hexal should be taken at the same time of day, usually in the morning, but Enalapril Hexal may be divided into two doses.

After the first dose, patient monitoring and regular BP measurement over the next few hours is recommended. If there is a high risk of arterial hypotension, such a patient should be given the first dose of Enalapril Hexal in a medical facility and the patient should be observed for at least 5 hours. The patient should be in the supine position during observation.

If the next dose of Enalapril Hexal is missed, the missed dose should be taken as soon as possible. If the next dose of Enalapril Hexal is approaching, you should skip the forgotten dose and take the next dose on time. The dose should never be doubled.
The dosing regimen is adjusted individually.

Interaction

The concomitant use of ACE inhibitors with other agents acting on the renin-angiotensin-aldosterone system (RAAS) increases the risk of arterial hypotension, hyperkalemia and impaired renal function (including acute renal failure).

As with other ACE inhibitors and angiotensin II receptor antagonists, co-administration of enalapril and aliskiren in patients with diabetes mellitus or renal impairment (CK less than 60 ml/min) is contraindicated.

Mutual potentiation in concomitant use of enalapril with other hypotensive agents.
Simultaneous use with nitroglycerin or other nitrates or other vasodilators, tricyclic antidepressants, neuroleptics, general anesthetics, narcotic drugs leads to increased antihypertensive effect.

Concomitant use of enalapril with diuretics (thiazide or “loop” diuretics) may increase the antihypertensive effect. Concomitant use of enalapril and potassium-saving diuretics (such as spironolactone, eplerenone, triamterene, amiloride), potassium preparations or potassium-containing salt substitutes, as well as other drugs that increase plasma potassium content (e.g., heparin) is not recommended.
Simultaneous use of nonsteroidal anti-inflammatory drugs (NSAIDs) (including selective cyclooxygenase-2 (COX-2) inhibitors) may weaken the antihypertensive effect of antihypertensive drugs due to the increased plasma potassium content, which leads to reversible renal dysfunction, fluid retention. Thus, the antihypertensive effect of angiotensin II receptor antagonists or ACE inhibitors may be weakened by NSAIDs, including COX-2 inhibitors.

NSAIDs and ACE inhibitors have an additive effect with respect to an increase in serum potassium, which may lead to impaired renal function, especially in patients with impaired renal function. This effect is reversible. Concomitant use should be used with caution in patients with impaired renal function.

The concomitant use of enalapril and lithium preparations is not recommended because the concentration of lithium in blood plasma increases and, accordingly, its toxic effects are intensified. When concomitant use of enalapril and lithium preparations the lithium concentration in blood plasma should be monitored.

Concomitant use with thiazide diuretics leads to increased concentration of lithium salts in blood plasma.
Concomitant use of enalapril with gold drugs for parenteral administration (sodium aurothiomalate) may cause a symptom complex including facial hyperemia, nausea, vomiting, arterial hypotension.
Weakens the effect of drugs containing theophylline.

Concomitant use with insulin and hypoglycemic agents for oral administration increases the risk of hypoglycemia.
Immunosuppressants, allopurinol, cytostatics increase hematotoxicity.

Drugs that inhibit bone marrow function increase the risk of neutropenia and/or agranulocytosis.
Ethanol increases the antihypertensive effect of enalapril.

Enalapril may be used concomitantly with acetylsalicylic acid (as an antiplatelet agent), thrombolytics and β-adrenoblockers. Concomitant use with other ACE inhibitors may increase the risk of hyperkalemia. Antacids may decrease the bioavailability of ACE inhibitors. Sympathomimetics may decrease the antihypertensive effect of ACE inhibitors.

Special Instructions

During treatment it is necessary to conduct regular monitoring of BP, heart rate and electrocardiogram, clinical blood tests, potassium, creatinine, urea, activity of “liver” enzymes in blood plasma, protein content in urine.

Patients with decreased volume of circulating blood (as a result of diuretic therapy, restriction of table salt intake, hemodialysis, diarrhea and vomiting) should be treated with caution – the risk of sudden and marked BP decrease after even initial dose of Enalapril Hexal is increased. Transient arterial hypotension is not a contraindication for continuation of treatment with Enalapril Hexal after BP stabilization. In case of repeated pronounced BP decrease the dose should be reduced or the drug should be discontinued.

In case of excessive BP decrease, the patient should be transferred to the supine position with low headrest; if necessary, 0.9% sodium chloride solution and plasma substitute drugs should be administered.

The use of dialysis membranes with high throughput (including AN69®) increases the risk of anaphylactic reaction. Adjustment of the dosing regimen on days free of dialysis should be made depending on BP.
Patients taking ACE inhibitors during low-density lipoprotein (LDL) apheresis with dextran sulfate have rarely developed anaphylactoid reactions. Therefore, this method should not be used in patients receiving ACE inhibitors.

Patients with decompensated chronic heart failure, coronary heart disease, cerebrovascular disease in whom a sharp decrease in BP may lead to myocardial infarction, stroke, or impaired renal function should be closely monitored.

The abrupt withdrawal of treatment does not lead to “withdrawal” syndrome (a sharp rise in BP).

In patients with ischemic heart disease or cerebral circulatory insufficiency treatment should be started with low doses of the drug.

Patients with diabetes mellitus with normoalbuminuria should note that Enalapril Hexal is only prescribed after determination of functional renal reserve, with micro- and macroalbuminuria – without prior determination. In patients with reduced renal function, the single dose should be reduced or the intervals between doses should be increased. In patients with diabetes mellitus the blood glucose concentration should be monitored regularly, especially against the background of hypokalemia.

During treatment with Enalapril Hexal, there may be increase of potassium in serum, especially in patients with chronic renal insufficiency, diabetes mellitus, in simultaneous prescription of potassium-saving diuretics (spironolactone, eplerenone, triamterene, amiloride are not recommended) or potassium preparations. These patients should be informed about the need to consult a physician in case of muscle weakness and arrhythmia.

The use of ACE inhibitors may result in dry cough. Cough episodes are persistent, but quickly disappear after discontinuation of the drug. This peculiarity should be taken into account in differential diagnosis of cough. If necessary, treatment may be continued.

During desensitization to wasp or bee venom, patients receiving Enalapril Hexal may develop hypersensitivity reactions. To avoid such reactions, temporary discontinuation of ACE inhibitor treatment before each desensitization procedure is recommended.

Before surgical procedures (including dentistry), the surgeon/anesthesiologist should be warned about the use of Enalapril Hexal.

In rare cases cholestatic jaundice occurs with the use of ACE inhibitors, with progression of which fulminant necrosis of the liver develops, sometimes with fatal outcome. If jaundice occurs and “liver” transaminases activity increases during the use of Enalapril Hexal, treatment should be discontinued. There have been cases of neutropenia/agranulocytosis, thrombocytopenia and anemia in patients taking ACE inhibitors.

In patients with normal renal function in the absence of other complications, neutropenia is rare. Enalapril Hexal should be used with great caution in patients with connective tissue diseases (including systemic lupus erythematosus, scleroderma) concomitantly receiving immunosuppressive therapy, allopurinol or procainamide, or with a combination of these factors, especially with existing renal dysfunction. These patients may develop severe infections that are not amenable to intensive antibiotic therapy.

If patients do take Enalapril Hexal, periodic monitoring of blood leukocytes is recommended. The patient should be warned to consult a physician if there are any signs of infection. If angioedema of the face occurs, withdrawal of therapy and administration of antihistamines to the patient is usually sufficient.

The angioedema of the tongue, pharynx or larynx can be fatal. If angioedema of the tongue, pharynx, or larynx can lead to airway obstruction, epinephrine (0.3-0.5 ml of epinephrine (adrenaline) solution subcutaneously at a ratio of 1:1000) should be given immediately and airway patency maintained (intubation or tracheostomy).

The incidence of angioedema is higher among patients of the Negro race receiving ACE inhibitor therapy than among patients of other racial backgrounds. Patients with a history of angioedema not associated with ACE inhibitor use have an increased risk of developing angioedema when taking any ACE inhibitor.
There is no experience of using the drug in patients after kidney transplantation, therefore treatment with Enalapril Hexal is not recommended in patients after kidney transplantation.
